Can Botox or Dysport Cause Permanent Damage?

Hi Eliza.  We have not heard of nor experienced the kind of "permanent damage" you are describing with Dysport and Botox.  What exactly did they say that was permanent?  

As for your case, the lazy left eye is a possible side effect (ptosis) but normally is gone very quickly within 4-6 weeks.  The other concerns you point out would have to be addressed in person as they do not sound consistent with side effects from a bad Botox injection. 

We have performed over 10,000 treatments of botulinum toxin injections in our clinic.  We have not yet seen any permanent or long term effects.  The biochemistry data shows conclusively that the effects are temporary.  When injected properly into muscles by a doctor who understands the anatomy of the facial muscles, the results are typically excellent with over 95% satisfaction.
